To all whom it may concern:

Be it known that l, G-nonon MoInrosH, a citizen of the United States, and resident of Stonington, in the countyof New London. and State of Connecticut, have invented certain new and-useful Improvements in Road- Indicators for Vehicles, of which the following is a specification.

This invention-relates to indicators and especially to that class en'iployed in the lo" cation of vehicles on roads and consisting of a frame carrying a map of the road which is being traversed by the vehicle and having mechanism connected with the moving parts of the vehicle for operating same and moving the map beneath apointer'which. indicates the exact location of the vehicle on-the map at that time. The device is also equipped with a register and indicator for exhibiting the number of miles traveled by the vehicle, as will be more fully explained in the following specification, set forth in the claims and illustrated in the drawings, wherein,-

Figur 1 is a side elevation of the device.

the lower end of the indicator. Fig. 1- is a cross sectional view. Fig. 5 is a view of a portion of the map removed from'the device.

The indicator is arranged within a box 5, having its front end open so that the map 6 may be exposed. This map is mounted on a, spool '7 and its end is passed between-rollers 8 and 9 which may be covered with any flexible material and capable of adjustment by means of the screws of the bearings 10 at each side of the box. To the shaft of the outer roller 8 is secured a worm wheel 11 which is actuated by means of a worm 1-2 on the shaft 13 journaled on the outside of the box 5 and having at one end a gear wheel 14 which may be connected with any of the moving parts of the vehicle for the purpose of driving the means for moving the map. As will be seen in Fig. 1, the wheel 11 is geared down to quite a degree and in practice it is preferable to rotate the shaft 13 one 11. By this means the map is caused to move very .slowly and the length of the frame and size of the map is carefully pro portioned for the speed of the machine. At the lower end of the box 5 is a second. set. of rollers 15 and lfidriven by means of a worm wheel 17 and worm 18 similar to, t-hnsg above described, and driven by'tii s'aine manic. 1

side of the wheel .side of the box, and this An indicator 18 may be arranged on the 17 to denote the-degree to which this wheel has been turned.

In the upper end. of the box is arranged a register 19 for recording the number of miles traveled by the vehicle, and is geared with the shaft 13 by means of the beveled wheels 20 and 21. This device may have the neccssary resetting knob 22 at one side' The location of the vehicle on the map is indicated by a finger 23 arranged to be shifted along a bar 24 secured to the upper finger is, in this instance,'shown as pointing the location of the vehicle on the middle road of the map. If the vehicle should turn into one of the adjacent roads, this road is carried parallel with the others on the map although it-inay cross the original roadiat right angles. This arrangement. of the roads is necessary in orderto fit the map into the device, and the finger 23 being-snugly fitted on the bar is capable of movement to indicate the position on one of the adjoining roads as shown by dotted lines in Fig. 2. I V

The map may be of any desired length and wound upon the spool '7, Besides the roads being indicated, prominent objects.

along the road may be illustrated such as, hotels, bridges, railroad crossings and any conspicuous objects which may serve to guide the occupant of the vehicle as it passes along the roadi a t is necessary that the moving parts be very delicately geared in order to indicate the exact position along the road which the finger travels, and to properly locate and move the map the parts must .be made in proper proportion andcorrespond with the moven'ients of the mechanism of the vehicle itself.

Vi hen it is desired to place another map in the device, it shaft '2" of the spool iay be slipped out r n i wound on the spool and if (lo red, the map may be placed in the oevice in its unwound stto and the movements of the parts reversed/so as to windnp the map. might also be performed in. case a return trip is bein made over the same road.

it is obvious that the parts may be other wise arranged and modified without departfrom the essential. features above descrioed.

What if claim as new is:--: 1. In a-roadmap indicator the combina- This reversingvehiclq of a. spool adapted to carry a tape map with roads arranged along the length of same and loosely journaled in the case,

unwinding rollers to engage the tape map 1 and draw it from the snool, means connected with the vehicle for driving the rollers and 15 a pointer to beset at any road on the map.

Signed at New York in the county of New York and'Stat-e of New York this 22d day of May A. l). 1912.
